Download or read book Environmental Contamination from Uranium Production Facilities and Their Remediation written by and published by . This book was released on 2005 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The legacies of past uranium mining and milling continue to be of concern and require assessment and remedial action. This problem has been recognized in many parts of the world over the past three decades, but has received increased attention since the end of the Cold War. Considerable effort and resources have been expended in dealing with this legacy. However, it has to be noted that the search for uranium has covered almost all countries on the globe. The result in some countries is a legacy of numerous small scale mines and mills. For economic and other reasons, including less stringent environmental standards and awareness at the time, these operations may not have been properly closed out and made safe. The remediation strategies and techniques developed by major problem holders, such as the USA or Germany, often would be out of scale for the problems in other countries. Therefore an international workshop was organized in Lisbon from 11 to 13 February 2004 as a forum for the exchange of views and experiences of countries with smaller scale uranium mining legacies.

Download or read book Nuclear Development Environmental Remediation of Uranium Production Facilities written by OECD Nuclear Energy Agency and published by Nuclear Energy Agency, Organisation for Economic Co-operation and Development. This book was released on 2002-02-27 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental remediation activities in uranium mines and mills have become increasingly important in the last few decades due to the large number of facilities which have been taken out of operation, the growing interest in remediating previously abandoned sites and the increasingly strict environmental regulations that are being put in place. Remediation programmes are being implemented to ensure the return of affected areas to previously existing environmental conditions or to a land use that will be sustainable in the long term and acceptable to all stakeholders. This report provides a summary of the most relevant issues and practices in remediation programmes of uranium production facilities and an overview of activities and plans in reporting countries. It covers the areas of site characterisation, dismantling and decommissioning, waste management facilities, water remediation, long-term stewardship and monitoring, policies and regulations, and costs. The country profiles of remediation activities and plans include information considered to be important by the country and are based on survey responses provided by 22 countries (12 OECD and 10 non-OECD countries).

Download or read book Assessment of Alternatives for Long term Management of Uranium Ore Residues and Contaminated Soils Located at DOE s Niagara Falls Storage Site written by and published by . This book was released on 1984 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: About 11,000 m3 of uranium ore residues and 180,000 m3 of wastes (mostly slightly contaminated soils) are consolidated within a diked containment area at the Niagara Falls Storage Site (NFSS) located about 30 km north of Buffalo, NY. The residues account for less than 6% of the total volume of contaminated materials but almost 99% of the radioactivty. The average 226Ra concentration in the residues is 67,000 pCi/g. Several alternatives for long-term management of the wastes and residues are being considered, including: improvement of the containment at NFSS, modification of the form of the residues, management of the residues separately from the wastes, management of the wastes and residues at another humid site (Oak Ridge, TN) or arid site (Hanford, WA), and dispersal of the wastes in the ocean. Potential radiological risks are expected to be smaller than the nonradiological risks of occupational and transportation-related injuries and deaths. Dispersal of the slightly contaminated wastes in the ocean is not expected to result in any significant impacts on the ocean environment or pose any significant radiological risk to humans. It will be necessary to take perpetual care of the near-surface burial sites because the residues and wastes will remain hazardous for thousands of years. If controls cease, the radioactive materials will eventually be dispersed in the environment. Predicted loss of the earthen covers over the buried materials ranges from several hundred to more than two million years, depending primarily on the use of the land surface. Groundwater will eventually be contaminated in all alternatives; however, the groundwater pathway is relatively insignificant with respect to radiological risks to the general population. A person intruding into the residues would incur an extremely high radiation dose.

Download or read book The Long term Safety of Uranium Mine and Mill Tailing Legacies in an Enlarged EU written by and published by . This book was released on 2008 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: The political changes from the late 1980s onwards have led Europe-wide to programmes for dealing with the uranium mining and milling legacies. A report drafted on behalf of the European Commission described the situation as it had developed by the end of 2005. With the EU having been enlarged since then, it appeared necessary to review the findings and conclusions of this report. The earlier report also did not provide conclusive thoughts on the long-term management of uranium mine and mill tailings. The present report -- reviews the current situation in Romania and Portugal, singled out in the earlier report as needing further attention. It is concluded that Portugal has made good progress, while the situation in Romania continues to be unclear; -- reviews the bearing that international regulations, such as the EC Environmental Impact Directive, and conventions, such as the Aarhus and Espoo conventions, might have on the management of uranium mine and mill tailings sites; -- also develops thoughts on the long-term management of uranium mining and milling sites that are not fit for free release. These thoughts are based on the current international discussion of the subject.

This book was released on 2017-04-25 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report assesses the levels and effects of exposure to ionizing radiation. Scientific findings underpin radiation risk evaluation and international protection standards. This report comprises a report with two underpinning scientific annexes. The first annex recapitulates and clarifies the philosophy of science as well as the scientific knowledge for attributing observed health effects in individuals and populations to radiation exposure, and distinguishes between that and inferring risk to individuals and populations from an exposure. The second annex reviews the latest thinking and approaches to quantifying the uncertainties in assessments of risk from radiation exposure, and illustrates these approaches with application to examples that are highly pertinent to radiation protection.

Download or read book Evaluation of Guidelines for Exposures to Technologically Enhanced Naturally Occurring Radioactive Materials written by National Research Council and published by National Academies Press. This book was released on 1999-02-25 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Naturally occurring radionuclides are found throughout the earth's crust, and they form part of the natural background of radiation to which all humans are exposed. Many human activities-such as mining and milling of ores, extraction of petroleum products, use of groundwater for domestic purposes, and living in houses-alter the natural background of radiation either by moving naturally occurring radionuclides from inaccessible locations to locations where humans are present or by concentrating the radionuclides in the exposure environment. Such alterations of the natural environment can increase, sometimes substantially, radiation exposures of the public. Exposures of the public to naturally occurring radioactive materials (NORM) that result from human activities that alter the natural environment can be subjected to regulatory control, at least to some degree. The regulation of public exposures to such technologically enhanced naturally occurring radioactive materials (TENORM) by the US Environmental Protection Agency (EPA) and other regulatory and advisory organizations is the subject of this study by the National Research Council's Committee on the Evaluation of EPA Guidelines for Exposures to Naturally Occurring Radioactive Materials.
